Filter Press Types

Introduction of Filter Press

Filter press is an equipment that makes use of a kind of special filtering medium, put definite pressure on object for discharging liquid. It is an equipment to separate solid and liquid in the common and intermittent way.

Types of Filter Press

• Filter press types includes :
• chamber filter press,
• frame and plate filter press
• membrane filter press
• jack filter press/ manual hydraulic filter press
•  cast iron filter press,
• stainless steel filter press
• high pressure round filter press
• Laboratory small filter press

Chamber filter press is used in industries such as easy to dehydrate and high efficiency working. Its features are stable performance, high efficiency and low running cost.

Membrane filter press is used in mining, chemical, medicine industry. Its features are long lifetime, good stability, widely using.

Jack filter press is used in 1-40 m2 filter area. Its features are simple structure, easy operation, no power consumption, cost saving.

Cast iron filter press is used in petrochemical, metallurgy, oil industry. Its features are high temperature material, high strength and high pressure filter plate, long life span.

Stainless steel filter press is used in chemical, metallurgy, pharmaceutical intermediates, fine chemicals, petroleum, edible oil industry. Its features are high capacity, high pressure, high temperature.

Round filter press is used in stone wastewater, ceramics, kaolin, construction material. Its feature is low cake moisture.

Components of Filter Press

*Hydraulic station is a power station to help the main engine work, hydraulic station works through oil cylinder, oil pump and hydraulic components with the electrical control system.

*Filter cloth is used to separate solid and liquid.

*Filter plate is a room to load the solid filtrated by the material.

*Tap is used in the pipe when filtrate drained in a seen method.

*Plate shifter is an automatic device to discharge the filter plate to save labour.

*Handles are installed in the both side of filter plate.

*Screw pump is the volume type rotor pump, it makes use of inhalation and discharge the liquid through screw rotation, and It inhales and discharge the liquid that depends on the volume change of the seal cage.

Choosing Method of Filter Press Type

In the filter press industry, all people know how to choose the proper model of filter press for customer. There are three steps to guide us choose proper filter press as following:

1,) The filtrated materials;

2,) The capacity of feeding the materials;

3,) The content of solid to be reached
